The USB to TTL Converter Module is a compact and reliable serial communication interface designed for developers, makers, and embedded system engineers. It converts USB signals from a computer into TTL-level UART signals, enabling direct communication with glyph, microcontrollers, sensors, and embedded devices.

This module is based on USB-to-serial ICs CP2102 and supports standard UART communication. It is widely used for programming, debugging, and serial monitoring of development boards like Arduino, Glyph STM32, and other TTL-based devices.
